NOTES: 1) All zones that are in alarm will be displayed simultaneously in the “circuit” area of the display.
Example: “1 2 Manual” would be displayed if all were in alarm.
2) If an alarm condition exists it will remain on the display. If more than one condition exists other than an alarm
condition, the display will be scrolled every 2 seconds.
3) The backlight on the LCD display is off when the AC power is off except when an alarm condition exists. If the
TEST SWITCH is operated during the absence of AC power, the backlight illuminates.
CONTROL SWITCHES
SILENCE SWITCH: Momentary switch silences built in buzzer and devices connected to the indicating appliance circuit.
This will not disable any visual or other alarm outputs such as the electronic outputs or the auxiliary
contacts. Any additional trouble or alarm conditions will reactivate the appropriate circuits.
RESET SWITCH: Momentary switch resets all alarm circuits if the condition has been corrected. Removes power from
the alarm initiating device circuit and also from the auxiliary power circuit if this mode has been
selected. The reset switch must be held for a minimum of 3 seconds. This is to avoid accidental
reset.
TEST SWITCH: Momentary switch activates all indicators, trouble, and alarm outputs. These all return to normal
when the switch is released. If the TEST SWITCH is operated during the absence of AC power, the
backlight illuminates.
ZONE DISABLE
SWITCHES: Supervised switches which disable the associated zone, inhibiting trouble and alarm outputs for the
specified zone (Zone 1 or Zone 2). Operating either of these switches will generate a system trouble
and a zone trouble. When the panel is operated in “cross zone” mode, disable either Zone 1 or Zone
2 to effectively disable both zones for an alarm condition.
AUTO RESET
SWITCH: A supervised switch which disables the latching feature of the alarm initiating device circuits for test
purposes. Operation of this switch will generate a system trouble.
RELEASING
CIRCUIT DISABLE
SWITCH: A supervised switch which disables the releasing circuit. Operation of this switch generates a system

BASIC CIRCUIT OPERATION
DESCRIPTION OF SEQUENTIAL MODE:
Actuation of one detector in any one zone will create an alarm condition. Actuation of a second detector in the same zone will
start the pre-discharge timer (this mode is usually used with smoke detectors).
DESCRIPTION OF CROSS-ZONING MODE:
Actuation of one or more detectors in any one zone will create an alarm condition. Actuation of one or more detectors in both
zones, in addition to creating an alarm condition will start the pre-discharge timer. This mode is usually used with smoke
detectors.
ALARM CONDITION:
Provided all associated switches are in their normal condition an increase of current on any alarm initiating device circuit to
approximately 15mA or greater will result in the following:
1) The zone or zones that have been activated will be displayed along with the word “ALARM” on the alpha-numeric
display.
2) Operation of the red alarm LED.
3) Operation of the auxiliary alarm contacts.
4) Positive 24 VDC will appear on the associated zone electronic output terminal.
5) Operation of one or both of the indicating appliance circuits depending on how they are programmed.
TROUBLE CONDITIONS:
Microprocessor failure: The yellow “System Trouble” indicator will be on; the “Trouble” buzzer will be pulsating and you will
be unable to silence the buzzer by operating the trouble silence switch. To silence the buzzer, disconnect the battery and turn off
the AC power. After 30 seconds reapply power. If the trouble still exists, call the factory. The supervision of the microproces-
sor is a safeguard feature that is built into the panel.
Other System Trouble: System trouble conditions will result in the following common trouble indications.
1) Operation of the system trouble LED.
2) Operation of the built-in trouble buzzer.
3) Operation of the auxiliary trouble contacts.
INITIATING DEVICE CIRCUITS RESPONSE:
A decrease in current to approximately 3 mA or operation of the zone disable switch to the disable position on any initiating
device zone will result in the following:
1) The zone or zones that are affected will be displayed along with the word “TROUBLE” on the alpha-numeric display.
If more than one trouble condition exists the conditions will be alternately scrolled every 2 seconds.
2) Operation of all of the common trouble outputs (see “Common Trouble Outputs”).
firealarmresources.com

12
PFC 2000RC •5403521-REV N•3/03

A decrease of current to approximately 1.5mA in the abort circuit will result in the following:
1) The words “ABORT” and “TROUBLE” will be displayed on the alpha-numeric display. If more than one trouble condi-
tion exists, the conditions will be alternately scrolled every 2 seconds.
2) Operation of all of the common trouble outputs (see “Common Trouble Outputs”).
INDICATING APPLIANCE AND RELEASING CIRCUITS RESPONSE:
An increase of current to approximately 8 mA or a decrease of the current to approximately 1.5 mA in either the indicating
appliance circuit or the releasing circuit, or connecting an indicating appliance backward will result in the following:
1) The zone or zones that are affected will be displayed along with the word “TROUBLE” on the alpha-numeric display. If
more than one trouble condition exists the conditions will be alternately scrolled every 2 seconds.
2) Operation of all of the common trouble outputs (see “Common Trouble Outputs”).
NOTE: A current in excess of 1.5 Amps on a indicating appliance circuit when the panel is in the alarm condition will result in
an indicating appliance circuit trouble as described above. Manual operation of the reset switch is required to correct the
trouble condition.
CAUTION: A problem in a device that is connected into the indicating appliance circuit may not be apparent when the panel is
in the normal condition. If the indicating appliance circuit indicates a trouble condition when the panel is in an alarm condition
the problem must be located and corrected.
SUPERVISORY CONDITION:
An increase in current to approximately 4.5 mA or greater in the supervisory circuit will result in the following:
1) The words “SUPV” and “SUPERVISORY” will be displayed on the alpha-numeric display. If more than one trouble
condition exists, the conditions will be alternately scrolled every 2 seconds.
2) Operation of all of the common trouble outputs (see “Common Trouble Outputs”).
3) The yellow supervisory LED will be lit.
4) Positive 24 Volts DC will appear on the associated electronic output terminal.
ABORT CONDITION:
An increase in current to approximately 4.5mA or greater in the abort circuit will result in the following:
